About the Role: 

We are hiring a Senior Engineer with in-depth expertise in the design, testing, and 

validation of battery packs for Battery Energy Storage Systems (BESS). This role 

will be responsible for developing safe, reliable, and high-performance lithium-ion battery 

pack systems—from cell selection and mechanical/electrical design to testing, validation, 

and compliance. 

The ideal candidate will work cross-functionally with R&D, manufacturing, and QA/QC 

teams to deliver battery pack solutions that meet performance, safety, thermal, and 

regulatory standards for grid-scale, commercial and industrial applications. 

Key Responsibilities: 

• Design battery pack architecture (cell-to-module, module-to-pack) 

including mechanical layout, electrical schematics, and thermal systems. 

• Select appropriate cells (LFP, NMC, etc.) based on application-specific 

performance and safety criteria. 

• Integrate and validate Battery Management Systems (BMS), thermal 

protection, contactors, and fuse logic. 

• Collaborate with mechanical design teams on enclosures, structural 

integrity, and thermal management. 

• Define and execute DFMEA, validation plans, and test protocols for pack-

level performance, lifecycle, thermal, and abuse tests. 

• Lead charge/discharge cycle testing, aging studies, and thermal runaway 

simulations. 

• Coordinate with external labs for certifications (e.g., UL 9540A, UN38.3, IEC 

62619, etc.). 

• Analyze test data for SoH, SoC, degradation, impedance, and thermal 

characteristics. 

• Generate detailed design reports, validation reports, and compliance 

documentation. 

• Work with component vendors (cells, BMS, thermal materials) for 

specifications, sourcing, and testing. 

• Interface with internal engineering, field, and manufacturing teams to 

integrate design feedback and optimize production feasibility 

Required Qualifications: 

• B.E./B.Tech or M.E./M.Tech in Electrical, Electronics, Power Systems, or Mechatronics. 
• 3+ years’ experience in battery pack design, thermal/electrical integration, and validation. 
• Deep understanding of Li-ion chemistry (LFP/NMC) , Li-ion cell behaviour, SoC/SoH metrics, and degradation mechanisms. 
• Strong knowledge of BMS design, CAN communication, and thermal runaway mitigation.
